1736 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1737 moved to level 0 and declared as static. Also they are explicit
1738 placed in access bank. This was necessery because some times they
1739 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1740 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1741 optimizations. Currently only compare to unsigned char is implemented,
1742 * src/pic16/gen.c: added fReturnIdx array,
1743 * (struct resolvedIfx) is moved to gen.h and made public,
1744 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1745 * (aopForSym): added an optimization to directly store in stack of
1746 the operand of a SEND iCode,
1747 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1748 but as registers instead (AOP_REG) using the fReturnIdx array,
1749 * (pic16_freeAsmop): remove the freed register from the
1750 _G.sregsAlloc field,
1751 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1752 a compare of 'WREG',
1753 * (pic16_popGetTempRegCond): changed function prototype, now
1754 function takes also a bitVector argument v which holds the current
1755 set of registers that are allocated for stack access by aopForSym,
1756 registers allocated in aopForSym for accessing stack symbols are not
1757 any more part of the functions usedRegs field,
1758 * (genCall): some times aopOp is called for a stack variable to be
1759 send, aopForSym might perform the push, if this is true make sure
1760 that genCall doesn't push the variable twice by testing _G.resDirect,
1761 * (genFunction): changed testing for unspecified interrupt number
1762 from 256 to INTNO_UNSPEC,
1763 * modified selection scheme of frame pointer generation. Previously
1764 if function did use local registers a frame pointer was generated,
1765 now a frame pointer is generated only if function has arguments
1766 (that need PLUSW2 register access), or has stack arguments, or the
1767 compiler is not instructed to omit the frame pointer,
1768 * (genEndFunction): before restoring local registers that were saved
1769 in the function preamble, also restore the registers that *might*
1770 have been allocated for stack access,
1771 * (genRet): removed some old comments,
1772 * (genCmp, the active (RN's) version): added a call to the
1773 pic16_genCmp_special function to perform the compare with a more
1774 robust and optimized way,
1775 * (genInline): a feature has been added in inline code generation,
1776 which allows a wildcard variable substitution when writing inline
1777 assembly. Code is incomplete and experimental therefore undocumented,
1778 * (genCast): changed order of aopOp for result and right to allow
1779 aopForSym to directly load the result if possible,
1780 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1781 perform an optimized compare on some selected special occasions,
1782 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1783 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1784 generate an IVT any more,
1785 * src/pic16/main.c (pic16_optionsTable): added command line option
1787 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1788 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1790 * src/pic16/NOTES: Raphael Neider added in list of active developers
1791 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1792 jumptable_end to prevent bug #,
1793 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1794 inCond and outCond fields,
1795 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1796 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1797 turn off register spilling,
1798 * (packRegsForOneUse): synced with other ports' versions although it
1799 is not used currently,
1800 * (pic16_packRegisters): added an optimization while reading
1801 structure bitfields, some registers may be saved (malloc code is
1802 decreased by 80 bytes)
1804 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1806 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1807 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1808 this can be optimized more?
1810 2005-03-10 Raphael Neider <rneider AT web.de>
1812 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1813 genNearPointerGet): (hopefully) fixed access to bitfields via
1814 pointers (p->bitN = x; and x = p->bitN; failed)

2140 access stack and frame pointers. They are initially assigned to
2141 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2142 accessing SFRs. Updated all occurences of modification of stack or
2143 frame pointer in gen.c and pcode.c,

2448 Adding support for replacing ljmps with sjmps in jumptables
2449 generated for switch statements. For now you need to set the
2450 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2451 Now 4 algorithms for mcs51 jumptable generation are used:
2452 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2453 addresses loaded pc-relative for up to 112 cases and stack-pushing
2454 target addresses loaded with offset from dptr for up to 256 cases.

2486 * added libc directory. The current version of LibC contains string
2487 functions, ctype functions and macros and some functions of the
2488 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2489 be extensively tested in the future. Standard disclaimer here.

2503 * (genCmp): experimental code for new genCmp which uses PIC18's
2504 special compare&skip instructions. Initial tests fail some times
2505 with variables grater than 1 byte in size, so new code is disabled,
2506 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2508 * (genCast): began a fix to optimize the casting of a bit to another
2509 bit, now assigning a bitfield to another bitfield will fail, sorry,

2523 registers when it shouldn't,
2524 * src/pic16/ralloc.c (allocReg): add preliminary support for
2525 supporting a limited set of temporary registers,
2527 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5535 loaded with the linker search paths (-L arguments) and the libraries
5536 to be linked with the current source (-l arguments). Changes
5537 currently will affect only the pic16 port.
5538 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5539 include path the port specific paths and port specific libraries,
5540 * gplink command now contains the $3 argument,
5541 * src/pic16/device.h,

5558 Documenting changes from previous commits.
5559 * configure.in (version 1.56),
5560 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5561 when generating output files to configure the pic16 library,
5562 but now I've commented it out, since gputils aren't installed in the
5563 SF compile farm, so library won't compile
5565 * device/lib/Makefile.in (version 1.56): initially I've added in
5566 target 'all' the prerequestive 'model-pic16' so it compiled the
5567 pic16 library, but now I've commented it out for the same reasons
5569 * added targets 'model-pic16' and 'objects-pic16' to compile the
5571 * added target 'port-specific-objects-pic16' to handle the
5572 generated libraries and copy them into the build/ directory
5573 * added target 'clean-intermediate-pic16' to clean intermediate
5574 files into pic16 directory
5575 * in target 'installdirs' added line to create directory pic16 in

5597 option so that it actually works. Made it specific to the z80, since
5598 the gbz80 doesn't have these kinds of I/O ports.
5600 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5822 LEFT_OP (left shift)
5824 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5826 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5827 (default behaviour).
5829 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5831 A python script to validate compiler diagnostic messages. It can be
5832 used to verify that sdcc complains about bad c source code and
5833 gives a good location of the error.
5834 * support/valdiag/Makefile,
5835 * support/valdiag/valdiag.py,
5836 * support/valdiag/tests/*

5853 Bug reported from Jesus Calvino-Fraga
5855 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5857 * sdcc.spec: updated
5858 * device/include/Makefile.in: don't install CVS directories
5859 * device/lib/Makefile.in: added removal of CVS directories after install
5860 * doc/Makefile: fixed install, added local_icons
5861 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5862 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5863 * src/ds390/gen.c (genRightShift): fixed bug #870788
5864 * src/SDCCast.c (decorateType): fixed bug #870781
5866 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5868 PIC16 port related changes:
5869 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5870 added variable stackPos,
5872 * gen.c: genCall, assignResultValue: added support for
5873 pushing/retrieving function parameters to/from stack,
5874 genFunction,genEndFunction: setup stack frame for the
5876 genAddrOf: will be changed according to bug 863624
5878 * added files genutils.c and genutils.h which contain gen*
5879 debugged and optimised functions extracted from gen.c
5881 * glue.c: added variable 'externs' which holds extern symbols,
5882 pic16emitRegularMap: is modified to properly handle relocatable
5883 symbols under the new scheme,
5884 pic16createInterruptVect: is modified
5885 pic16printPublics: is modified to emit 'global' assembler directives,
5886 added pic16_printExterns to print extern symbols,
5887 pic16glue: initializes stack/frame pointer in the beginning of
5888 the assembly output. Temporary hack, will be corrected later,
5889 because gplink yet does not support stack and SDCC does not
5890 yet support a type of crt0.o object to create the final binary.
5892 * Removed many lines that contain 8051 legacy code.
5893 * The code is finally placed under a 'code' directive.
5894 * Added port specific options.
5896 * _process_pragma: simplified since now we do not need *special*
5897 include file to define SFR registers. But a separate header
5898 will be needed. This will be developed later.
5899 * _pic16_parseOptions: added, parses port specific options:
5900 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5901 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5902 --preplace-udata-with=
5904 * _pic16_setDefaultOptions: modified to initialize section names,
5905 but hack is temporarly out of order since it needs improvement.
5906 * _pic16_genAssemblerPreamble: configuration words are emitted by
5907 their address instead of their name. This part is incomplete and
5908 supports only the 18Fxx2 devices. Other devices will emit an error
5909 during assembly since they do not contain the same set of config
5911 * _pic16_genIVT: is modified,
5913 * pcode.c: added definitions for some hardware registers that are needed
5915 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5916 All PCI entries are updated. Now LFSR is supported.
5917 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5918 * added pic16_newpCodeOpLit2 to support instructions with
5919 two literal arguments
5920 * pic16_pCode2str: corrected code that emits assembler instructions
5921 with two literal operands and those that have an access bit modifier
5922 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5923 this fixes a bug which caused some labels to be lost, when an
5924 assembler directive was added, i.e. banksel,
5925 * pic16_FixRegisterBanking: improved logic that causes the insertion
5927 * InlineFunction: functions that are called once, are not any more
5928 inlined. This can be a port option in the future,
5930 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5932 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5933 hold the corresponding uninitialized symbols,
5934 * pic16_allocProcessorRegister: registers have explicit marked the
5936 * pic16_allocInternalRegister: registers are explicit marked as
5938 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5939 processing list, so bit registers were lost,
5942 * ralloc.h: added field 'accessBank' and original symbol operand
5943 in register definition,
5944 * removed the field isMapped from register definition,
5946 ** Several functions have been removed from various sources:
5947 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5948 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5949 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5950 pic16_assignRelocatableRegisters
5952 ** others have been introduced:
5953 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5954 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5956 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5958 * support/scripts/inc2h.pl: changed definition of BIT_AT
5959 to emit 'sbit at' instead of 'bit at'. This was a request.
5961 PIC16 port related preliminary changes:
5962 * gen.c: prefixed function popRegFromString with
5963 pic16_ and all references to it corrected
5964 * pcode.c: all pic16_pc_* hardware registers prefixed
5965 with underscore (_),
5966 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5967 * ralloc.c: newReg(): when register is REG_SFR then
5968 set address to rIdx,
5969 pic16_allocProcessorRegister(): marks register wasUsed=0
5970 pic16_writeUsedRegs(): added a call to assign processor
5971 registers via pic16_assignFixedRegisters
5973 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5975 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5976 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5977 variables in unused register banks. Also the SSEG is placed
5978 wherever there is enough space for it, and IDATA can be anywhere
5979 in internal RAM. For now compile using -Wl-Y[stack_size].
5980 The mem file is different for this option as well, since it
5981 makes no sense of talking about DSEG lenght.
5983 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5985 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5986 in certain cases, e.g. when ROM assignment, patch provided
5987 from Albert den Haan.
5989 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6992 fetching of the pointer
6993 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6994 copied from genNearPointerSet()
6995 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6996 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7012 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7013 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7014 type for bits was changed. It resulted in bit variables becoming
7015 global, which is not permitted in PIC 14 assembly output.
7017 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7032 A few small changes that speed up the peephole optimizer.
7036 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7038 Try to make the peephole optimizer smarter by maintaining
7039 an association between the assembly source code and the
7040 iCodes that originated them. Put this information to use
7041 with a new peephole rule condition "notVolatile" so that
7042 the rules can be aggressive yet still safe.
7047 * src/mcs51/peeph.def
7049 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7053 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7054 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7055 if the left or right operand symbols have the accuse flag set.
7057 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7059 Changed the type of the result of the ! (NOT) operator to char;
7060 previously it returned the same type as the source. This allows
7061 us to eliminate all the genFloatNot functions (all of its target
7062 implementations were very buggy) since !float can use the same

7074 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7075 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7076 during interrupts. Ensure WSAVE is located at a shared bank address.
7077 2. Fixed page selection in some places
7078 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7079 the registers name strings.
7080 4. Fixed "signed / unsigned compare" compiler warnings.
7081 5. The PIC port manages its own allocation of the general purpose
7082 registers, but makes no attempt to reuse them. As a result when
7083 compiling it soon runs out of general purpose registers. Some
7084 additional code was added to the files pcode.c and device.c to walk
7085 through the function call tree and rename the registers so that they
7095 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7102 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7104 Made bitfield a distinct type from bit so that bitfields
7105 convert as per ANSI C and bits retain their traditional
7106 boolean style behaviour. Implemented bitfield support in
7114 * src/ds390/gen.c: bit v bitfield split
7115 * src/z80/gen.c: New support for bitfields
7116 * support/regression/tests/bitfields.c: reenabled z80,
7119 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7121 Rules 246.x, 247.x relate to bitfields, the others speed up
7122 access to xdata mapped I/O devices.
7124 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7126 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7128 Cleaned up genPackBits and genUnpackBits and added two helper
7129 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7130 for literal assignments in genPackBits (thanks to Frieder for
7136 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7138 Fixed bug #748310 (pointer to function type mishandled when the
7139 function name is omitted). Also fixed a SIGSEGV when a function
7140 attribute (reentrant, etc) is used on a non-function or on a
7141 function but misplaced before the parameter list.
7143 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7145 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7146 * support/Util/SDCCerr.h,

7170 Made the constant following the "interrupt" keyword optional. If
7171 omitted, the function will not automatically be given an entry
7172 in the interrupt vector table (similar to #pragma NOIV, but
7173 less syntacticly kludgy). The interrupt number is also now
7174 range checked. Also fixed a bug in the high order bit example

7704 added if/endif conditional macros to remove options help
7705 messages from optionsTable when a port is not configured, added
7706 support for the PIc16 port in the ports table, when executing
7707 the compiler with no port specified on command line, a default
7708 port is selected with the new macro DEFAULT_PORT which is
7709 defined in port.h, in setDefaultOptions() linkOptions is removed
7710 from initialization assignment, since now it is a set,
7711 parseCmdLine uses setParseWithComma for linkOptions, in
7712 linkEdit() linkOptions are accessed with new function indexSet()
7713 which returns the i'th item of a set variable. See SDCCset.c, in
7714 linkEdit() when calling buildCmdLine(), added linkOptions as
7715 last argument. Now users can pass arguments to gplink via the
7716 -Wl option, main() uses pic16glue() to glue up pic16 programs

7730 gpasm complaining and test the linkage with gplink, _linkCmd and
7731 _asmCmd changed to be more gplink and gpasm friendly
7732 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7733 produced an error when parsed, peep rule 12 is added to utilize
7734 movff, but it is commented out since the pCode does not support
7735 yet a command with 2 address arguments
7737 2003-05-18 <johan AT balder>
7739 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7759 on entry now. Add tbreak. Other enhancements and fixes for use
7762 2003-05-12 Borut Razem <borut.razem AT siol.net>
7764 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7766 2003-05-11 Borut Razem <borut.razem AT siol.net>
7768 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7769 the path of bin directory, so that PATH is the only env. variable, which has to be set
7770 in case of standard installation.
7771 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8798 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8800 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8802 * in \sdcc\as\mcs51\ changed these files in order to create an
8803 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8804 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8805 following files to include the previous two files: aslink.dsp,
8806 Makefile.aslink, Makefile.bcc, and Makefile.in.
8808 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8809 .adb instead of .cdb
8811 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8813 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8814 value from option --iram-size.
8816 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8818 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8821 2002-09-18 <wiml AT hhhh.org>
8823 * SDCClrange.h: exposed setFromRange() and setToRange()
8824 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8825 packRegsForAccUse() (bug 542397)
8826 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8827 multiple times and emitting the fetch operations more than once
8828 added aopGetUsesAcc() function to allow binary operators to
8829 fetch their operands in the correct order; made genMinus() emit
8830 compact code for X = LITERAL - Y
8832 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8833 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8834 sprintf() in line 1267.
8836 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8837 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8840 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8841 Changes to aslink (All the changes are marked with 'JCF'):
8843 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8846 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8847 area BSEG. Also moves, if possible, the DATA area down into the internal
8848 ram so more space is available.
8850 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8853 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8854 not bytes. Function summary() which creates a memory usage summary
8855 file with extension .mem. Reports of overlaping stack and small stack
8856 size. If the space for the stack is less than 16 bytes aslink trows a
8859 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8860 the 8051. Option 'y' for memory summary output file.
8862 Changes to sdcc (All the changes are marked with 'JCF'):
8864 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8866 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8867 overlaying area for it (uses RegBankUsed[4]).
8869 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8870 bank zero as used by default. By default aslink locates the stack
8871 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8872 the creation of the .mem file. Delegates the allocation of data area
8873 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8874 the begining of the stack area to aslink.
8876 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8877 glue() in SDCCglue.c creates an area for it.
8879 2002-09-03 Borut Razem <borut.razem AT siol.net>
8880 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8881 sdcc/src/pic/glue.c:
8882 introduced atexit() handler for teporay files removal in case of
8883 errors, assertions, ...
8885 2002-08-29 Borut Razem <borut.razem AT siol.net>
8886 * sdcc/support/cpp2/auto-host_vc_in.h:
8887 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8888 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8889 Maybe there is a similar problem with BORLANDC? It should be checked!
8891 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8892 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8893 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8894 was not executed, and the compiler (cl) launched a warning:
8895 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8897 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8898 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8900 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8901 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8903 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8904 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8905 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8906 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8907 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8908 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8909 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8910 - added Release configuration in VS projects
8911 - review of compiler an linker options
8912 - VC .exe files are generated in bin_vc directory, not to interfere
8913 with binaries generated from other projects (cygwin, mingw, bcc ...)
8915 * sdcc/src/yacc.dsp: added
8917 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8918 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8919 and insert the version number definitions from .version
8921 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8923 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8924 added - genarate auto-host.h using auto-host_vc_in.h as template
8927 removed from CVS, generated automatically
8929 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8930 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8932 2002-08-11 Borut Razem <borut.razem AT siol.net>
8933 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8935 2002-08-10 Borut Razem <borut.razem AT siol.net>
8936 * src/SDCCmain.c (main):
8937 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8938 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8939 The consequence was that some temporary files were not removed.
8942 unification of code in functions tempfilename() and tempfile():
8943 function tempnam() is defined in Visual Studio 6.0 and .NET
8945 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8947 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8948 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8949 - removed compiler command line option /WX: Treats all warnings as errors
8950 - update a list of source files, included into the project
8952 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8953 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8954 changed project type to Generic Project so that can be correcly converted to VS.NET project
8956 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8958 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8960 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8962 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8963 added return 0 statements after assert() to make compiler happy
8965 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8966 added newline in the def file to keep MSC compiler satisfied
8968 * sdcc/src/z80/gen.c:
8969 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8970 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8971 - solved MSC error in function aopDump()
8973 * sdcc_vc.h: define PREFIX as "\\sdcc"
8975 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8976 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9019 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9021 Added "char *Processor" field to the port structure.
9024 Added -p option. Allows port dependent processor to be specified.
9027 Initialized the new field char *Processor field to NULL in all ports
9030 Compiler generated registers for interrupt context saving
9031 were not getting allocated.
9033 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9036 Fixed left shift. Will promote the left side of a left shift
9037 if a) left shifting more than size of operand or b) when assigned
9038 to something size > size of left side
9040 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9042 tons of changes. Register allocation has been
9043 rewritten. Added customization for the various PICs. Flow

9150 * sdcc/src/SDCCloop.c:
9151 Previous fix was not good. basic blocks that have "break" or "return" are
9152 not really partof a loop , but live ranges used in these blocks should
9153 be live thru the entire loop, so set partOfLoop but don't add them to
